We have not been able to test the Irix 5 port since March 2000,
|
|
due to lack of access to an Irix 5 machine.
|
|
|
|
On Irix 5, it is not possible to use both gcc's non-local gotos and
|
|
position-independent code (which is required for shared libraries).
|
|
The Mercury auto-configuration script should resolve this problem
|
|
by disabling the use of gcc's non-local gotos (e.g. the `asm_fast.gc'
|
|
grade).
|
|
|
|
Use of non-local gotos on Irix 5 was supported in previous releases of
|
|
Mercury, but now we recommend using the hlc.gc grade instead.
|
|
|
|
If you install from the source distribution, the initial version of the
|
|
compiler will use grade reg.gc. You can get a faster compiler by
|
|
adding the directory for the installed mmc to your PATH and then
|
|
reinstalling from the source distribution. The second time around,
|
|
the configure script will detect that a working mmc is in your PATH
|
|
and will build the compiler in grade hlc.gc rather than grade reg.gc.
